The Cygnus Wall is the "Central America" portion of the North American Nebula, and is rich in star-forming regions.

This image was intended as a false-color narrowband with RGB stars, but on processing the RGB data, there was enough nice nebulosity that I decided to keep that too. Fortunately Astro Pixel Proccessor's "Combine RGB" tool has presets for this and a lot of other setups besides. I chose HSORGB, which would map the narrowband Ha and OIII onto corresponding parts of the spectrum, with sulfur showing as green instead of deep red. I didn't touch a thing once I saw the initial color balance that APP produced.

Everything up to that point was in Astro Pixel Processor. I took the somewhat idiosyncratic route of combining the RGB data with its stars, running Spectrophotometric Color Calibration to balance it via catalog star colors, extracting the stars via StarXTerminator, and then extracting new R, G, and B mono images from the starless result. This gave me calibrated RGB nebulosity. I knew it would be overwhelmed by the bright narrowband channel images but I thought it gave a really nice result.

I really, really liked the starless image, where you could easily see the structure in the nebulosity without the distracting stars. So I toned down the stars for the complete image, and provide the starless one too for your pleasure.
